Description

Technical Field

[0001] The invention belongs to the technical field of positioning tooling, and in particular relates to a positioning tooling for processing brake discs of new energy vehicles. Background Art

[0002] The car brake disc refers to the annular component in the disc brake system, which rotates with the wheels while the vehicle is driving. When the driver steps on the brake pedal, the brake caliper clamps the brake disc to generate braking force, thereby stopping the wheels from rotating and stopping the vehicle.

[0003] Automobile brake discs need to be fixed during the processing, so a fixture is needed. The existing Chinese utility model patent (CN 111843885 B) discloses an automobile brake disc processing and positioning fixture. When in use, the first liquid inlet hole on the first rod and the second liquid inlet hole on the third rod are connected to a hydraulic system. The hydraulic system controls the extension and contraction of the hydraulic cylinder, the horizontal movement of the second rod, and the vertical movement of the sliding column, so that the second rod drives the third rod to clamp the side wall of the automobile brake disc, and the sliding column drives the clamping block to clamp the upper end of the automobile brake disc.

[0004] The above method can clamp the side wall and the top of the automobile brake disc, thereby improving the fixing effect of the automobile brake disc. However, the clamping block is always facing the placement direction of the automobile brake disc, and the clamping block will occupy the placement space of the automobile brake disc, thereby reducing the utilization rate of the placement space of the automobile brake disc on the positioning tool. When taking and placing the automobile brake disc, the automobile brake disc is easy to collide with the clamping block, and there is a problem of damaging the automobile brake disc and the clamping block. In addition, when the existing automobile brake disc processing positioning tool is in use, it is necessary to use a hydraulic system to drive the hydraulic cylinder, the second rod and the sliding column as driving parts, resulting in more driving parts and the use of the positioning tool is more complicated. Summary of the invention

[0005] The purpose of the embodiment of the present invention is to provide a new energy vehicle brake disc processing and positioning tooling, aiming to solve the problem that the vehicle brake disc is easily collided with the clamping block when taking and placing the vehicle brake disc, thereby damaging the vehicle brake disc and the clamping block.
